DeRay McKesson the prominent activist and late entrant into Baltimore’s mayoral race, will meet with President Barack Obama and civil rights leaders at the White House on Thursday for an event honoring Black History Month.

Mckesson, a former school administrator and Black Lives Matter protester who co-founded We the Protestors and Campaign Zero, will attend the meeting along with Al Sharpton, Cornell Brooks, president of the NAACP, and Democratic Rep. John Lewis of Georgia.

A White House official described the meeting as a first-of-its-kind gathering of leaders who represent different generations of the civil rights movement, and said the discussion will focus on criminal justice reform and building trust between police and neighborhoods.

Attorney General Loretta E. Lynch will also attend.

Mckesson, who lives in North Baltimore, gained widespread attention during protests after the police-involved shooting of Michael Brown in Ferguson, Mo., in 2014. He unexpectedly jumped into the race for Baltimore’s mayor earlier this month.

But Obama will skip the funeral of former Supreme Court Justice Antonin Scalia on Saturday.
